Technical Field
The patent of the utility model relates to a heating does not burn cigarette production technical field, concretely relates to contains bellied support element of fold and contains its cigarette.
Background
Along with the attention of consumers to health problems and the improvement of the demand of individualized experience of cigarette products, the tobacco industry continuously responds to the demand upgrade of consumers and develops various cigarettes with tar and harm reduction. The cigarette heating mode of the non-combustion type cigarette is different from that of the traditional cigarette product, so that the cigarette heating mode can meet the sensory requirements of consumers on the cigarette product and provide healthier smoking experience.
The existing heating non-combustible cigarette mainly comprises a smoking core material unit, a hollow supporting element, a cooling unit and a filter tip unit, wherein the hollow supporting element not only supports the cigarette, but also collects the smoke and assists the cooling unit to cool the smoke. The prior art forms the ventilation hole through breaing through cavity supporting element pipe wall, makes the outside air get into cavity supporting element inside and mix with the flue gas to increase the smog volume, effectively reduce the flue gas temperature, but its cooling effect to the flue gas and the mixed effect that makes air and flue gas are still not good, because following two points: 1. the contact area between the flue gas and the pipe wall of the hollow supporting element is limited, and effective cooling cannot be realized; 2. the air flow path of the flue gas and the air in the hollow supporting element is a straight line, the residence time in the hollow supporting element is short, and the flue gas and the air directly and quickly enter the cooling unit through the hollow supporting element and cannot be fully mixed. Consequently, in order to further realize the cooling to the flue gas, at present mainly improve or directly increase the quantity of cooling material to the cooling material of cooling unit, but the cooling material is mostly phase change material, and several mouths are being inhaled, and phase change material collapses and plug up airflow channel, and the resistance of inhaling risees by a wide margin, influences the suction and experiences.
Therefore, it is desirable to develop a hollow supporting element with strong supporting force and cooling effect to assist the cooling unit to achieve better cooling effect on the flue gas, even to replace the cooling unit.
The present invention is proposed in order to solve the above problems.
